JOHANNESBURG (AP) — A crowd stampeded at a football stadium in Angola on Friday, leaving at least 17 people dead and dozens injured.

The accident happened in the northwestern town of Uige when hundreds of people rushed at one of the stadium gates, causing some to fall and be trampled underfoot, according to Angolan and Portuguese media.

Some of the dead were children who suffocated in the stampede, the Portuguese news agency Lusa said. Lusa and Angop, Angola’s state-run news agency, reported a death toll of 17.

Angolan President Jose Eduardo dos Santos expressed condolences to the families of the victims, and instructed officials to assist the injured and open an investigation, Angop reported.

Spectators had gone to the stadium to watch the inaugural game between home team Santa Rita de Cassia and Recreativo de Libolo in the national Girabola competition.
